Some things, in no specific order, that I'd like to fix: |
4 |
|
(Some items in this list are perhaps already fixed.) |
5 |
|
|
6 |
Testing for the next release (0.4.5.1): |
M88K: |
7 |
|
o) Neither NIP nor FIP valid in rte? |
8 |
TEST DISK OVERLAY IMAGES |
o) FIP != NIP + 4, in rte! (Simulate delayed branch stuff.) |

11 |
|
o) CMMUs: |
12 |
# NetBSD/pmax 3.1 or 1.6.2 OK |
o) Translation invalidations, could be optimized. |
13 |

Some things, in totally random order, that I'd like to fix: |
|
|
(Some items in this list are possibly out-of-date by now.) |
|
|
|
|
|
Dyntrans: |
|
|
x) Instruction combination collisions? How to avoid easily... |
|
|
x) Think about how to do both SHmedia and SHcompact in a reasonable |
|
|
way! (Or AMD64 long/protected/real, for that matter.) |
|
|
x) 68K emulation; think about how to do variable instruction |
|
|
lengths across page boundaries. |
|
|
x) Dyntrans with valgrind-inspired memory checker. (In memory_rw, |
|
|
it would be reasonably simple to add; in each individual fast |
|
|
load/store routine = a lot more work, and it would become |
|
|
kludgy very fast.) |
|
|
x) Dyntrans with SMP... lots of work to be done here. |
|
|
x) Dyntrans with cache emulation... lots of work here as well. |
|
|
x) Remove the concept of base RAM completely; it would be more |
|
|
generic to allow RAM devices to be used "anywhere". |
|
|
o) dev_mp doesn't work well with dyntrans yet |
|
|
o) In general, IPIs, CAS, LL/SC etc must be made to work with dyntrans |
|
|
x) Redesign/rethink the delay slot mechanism used for e.g. MIPS, |
|
|
so that it caches a translation (that is, an instruction |
|
|
word and the instr_call it was translated to the last |
|
|
time), so that it doesn't need to do slow |
|
|
to_be_translated for each end of page? |
|
|
x) Program Counter statistics: |
|
|
Per machine? What about SMP? All data to the same file? |
|
|
A debugger command should be possible to use to enable/ |
|
|
disable statistics gathering. |
|
|
Configuration file option! |
|
|
x) Breakpoints: |
|
|
o) Physical vs virtual addresses! |
|
|
o) 32-bit vs 64-bit sign extension for MIPS, and others? |
|
|
x) INVALIDATION should cause translations in _all_ cpus to be |
|
|
invalidated, e.g. on a write to a write-protected page |
|
|
(containing code) |
|
|
x) 16-bit encodings? (MIPS16, ARM Thumb, 32-bit SH on SH64) |
|
|
x) Lots of other stuff: see src/cpus/README_DYNTRANS |
|
|
x) Native code generation backends: |
|
|
o) think carefully about this. |
|
|
o) simple syntax for emitting opcodes; backend implementation |
|
|
must be optional, so I don't have to write more code |
|
|
than necessary. after all, the non-native (C) code should |
|
|
always work. |
|
|
o) convert into native code only after an entire |
|
|
block has been translated? probably best. |
|
|
o) the "almost native" opcodes may be rearranged, |
|
|
"peep-hole optimized", etc. and then as a separate step |
|
|
this list of almost native opcodes is written out |
|
|
as native code. |
|
|
o) think about delay slots at the end of a block! |
|
|
o) x86/amd64 code generator can be very similar... perhaps |
|
|
o) NOTE that generation is per _ABI_, not per host arch! |
|
|
the configure script must detect ABI!!! |
|
|
o) branches to already translated code blocks can |
|
|
link the blocks together |
|
|
o) load/store are the most important to optimize |
|
|
|
|
|
Simple Valgrind-like checks? |
|
|
o) Mark every address with bits which tell whether or not the address |
|
|
has been written to. |
|
|
o) What should happen when programs are loaded? Text/data, bss (zero |
|
|
filled). But stack space and heap is uninitialized. |
|
|
o) Uninitialized local variables: |
|
|
A load from a place on the stack which has not previously |
|
|
been stored to => warning. Increasing the stack pointer using |
|
|
any available means should reset the memory to uninitialized. |
|
|
o) If calls to malloc() and free() can be intercepted: |
|
|
o) Access to a memory area after free() => warning. |
|
|
o) Memory returned by malloc() is marked as not-initialized. |
|
|
o) Non-passive, but good to have: Change the argument |
|
|
given to malloc, to return a slightly larger memory |
|
|
area, i.e. margin_before + size + margin_after, |
|
|
and return the pointer + margin_before. |
|
|
Any access to the margin_before or _after space results |
|
|
in warnings. (free() must be modified to free the |
|
|
actually allocated address.) |

|
Dyntrans: |
224 |
|
x) For 32-bit emulation modes, that have emulated TLBs: tlbindex |
225 |
|
arrays of mapped pages? Things to think about: |
226 |
|
x) Only 32-bit mode! (64-bit => too much code) |
227 |
|
x) One array for global pages, and one array _PER ASID_, |
228 |
|
for those archs that support that. On M88K, there should |
229 |
|
be one array for userspace, and one for supervisor, etc. |
230 |
|
x) Larger-than-4K-pages must fill several bits in the array. |
231 |
|
x) No TLB search will be necessary. |
232 |
|
x) Total host space used, for 4 KB pages: 1 MB per table, |
233 |
|
i.e. 65 MB for 32-bit MIPS, 2 MB for M88K, if one byte |
234 |
|
is used as the tlb index. |
235 |
|
x) (The index is actually +1, so that 0 means no hit.) |
236 |
|
x) "Merge" the cur_physpage and cur_ic_page variables/pointers to |
237 |
|
one? I.e. change cur_ic_page to cur_physpage.ic_page or something. |
238 |
|
x) Instruction combination collisions? How to avoid easily... |
239 |
|
x) Think about how to do both SHmedia and SHcompact in a reasonable |
240 |
|
way! (Or AMD64 long/protected/real, for that matter.) |
241 |

249 |
|
x) Remove the concept of base RAM completely; it would be more |

251 |
|

253 |
|
x) Redesign/rethink the delay slot mechanism used for e.g. MIPS, |
254 |
|
so that it caches a translation (that is, an instruction |
255 |
|

260 |
|
A debugger command should be possible to use to enable/ |
261 |

262 |

263 |
|
x) Breakpoints: |
264 |
|
o) Physical vs virtual addresses! |
265 |
|
o) 32-bit vs 64-bit sign extension for MIPS, and others? |
266 |
|
x) INVALIDATION should cause translations in _all_ cpus to be |
267 |
|

268 |

269 |
|
x) 16-bit encodings? (MIPS16, ARM Thumb, 32-bit SH on SH64) |
270 |
|
x) Lots of other stuff: see src/cpus/README_DYNTRANS |
271 |
|
x) Native code generation backends: |
272 |
|
o) calculate at runtime whether or not chunks of emulated |
273 |
|
(physical) memory are worth translating to native code |
274 |
|
(it is assumed that it has high overhead) |
275 |
|
o) experiment with calling the host's cc and ld externally; |
276 |
|
extremely high overhead, but could be interesting none- |
277 |
|
theless. |
278 |
|
o) experiment with using LLVM, or GNU Lightning? |
279 |
|
o) Important cases to think about: |
280 |
|
x) loads/stores |
281 |
|
x) delay branches |
282 |
|
x) other kinds of calls, branches |
283 |
|
o) branches to already translated code blocks can |
284 |
|
link the blocks together (block-chaining), although |
285 |
|
I'll probably want to wait with this until other |
286 |
|
things work. |
287 |
|
o) The first tests should be done with "testm88k", because |
288 |
|
that does not affect other modes. |

Simple Valgrind-like checks? |
314 |
|
o) Mark every address with bits which tell whether or not the address |
315 |
|
has been written to. |
316 |
|
o) What should happen when programs are loaded? Text/data, bss (zero |
317 |
|
filled). But stack space and heap is uninitialized. |
318 |
|
o) Uninitialized local variables: |
319 |
|
A load from a place on the stack which has not previously |
320 |
|
been stored to => warning. Increasing the stack pointer using |
321 |
|
any available means should reset the memory to uninitialized. |
322 |
|
o) If calls to malloc() and free() can be intercepted: |
323 |
|
o) Access to a memory area after free() => warning. |
324 |
|
o) Memory returned by malloc() is marked as not-initialized. |
325 |
|
o) Non-passive, but good to have: Change the argument |
326 |
|
given to malloc, to return a slightly larger memory |
327 |
|
area, i.e. margin_before + size + margin_after, |
328 |
|
and return the pointer + margin_before. |
329 |
|
Any access to the margin_before or _after space results |
330 |
|
in warnings. (free() must be modified to free the |
331 |
|
actually allocated address.) |
